If you like coffee, here is a delightful taste of confirmation bias. If you usually make fun of epidemiology, put your skepticism back in the pot, because coffee reduces diabetes.

As many as 380 million people worldwide have diabetes, with an economic estimate of up to $548 billion, making it one of the most significant global health problems in terms of pretend money no one earned. 
The Institute for Scientific Information on Coffee (ISIC) has brewed up its annual diabetes report outlining the latest research on coffee and type 2 diabetes and its delicious news. 

The research round up report concludes that regular, moderate consumption of coffee may decrease an individual's risk of developing type 2 diabetes. Key research findings include:

Most of the world that has access to the Internet knows two things about the Rosetta mission - it landed on a comet and a European engineer wore an ugly shirt that offended a lot of American women on Twitter.

The least interesting news is that the ESA now knows that if women can't wear bathing suits to represent them on television, then male project scientists cannot wear bowling shirts and shorts. The important news, however, is that mankind has shown we can go on a 10 year, 4 billion mile journey through the solar system and land on a rock the size of Cork City, Ireland.

We may talk about a battle of the sexes when it comes to our species, but in the rest of the primate world, it really is a battle. We have the luxury of cultural hand-wringing about the shirt a Rosetta mission engineer wore in a YouTube video, but when it comes to chimpanzees, a shirt is the least of female problems.

Male on female violence among chimpanzees is frequent - and it has to do with sex. 

Frightening experiences stick with us but a new study finds that the bonding hormone oxytocin inhibits the fear center in the brain and allows fear stimuli to subside more easily. 

Whether playing video games has negative effects is something that has been debated for 30 years, in much the same way that rock and roll, television, and even the novel faced much the same criticisms in their time.

Purported negative effects such as addiction, increased aggression, and various health consequences such as obesity and repetitive strain injuries tend to get far more media coverage than the positives. I know from my own research examining both sides that my papers on video game addiction receive far more publicity than my research into the social benefits of, for example, playing online role-playing games.

With over one billion people worldwide using social media, including 80 percent of employees using private sharing sites at work, members have been scrambling to insist that not only does it not negatively affect their work performance, but that it improves it. Yahtzee! probably wishes they could get the kind of free public relations Twitter gets.

Few studies have been done to examine the issue. Postdoctoral Fellow Dr. Cecilie Schou Andreassen and colleagues at the University of Bergen looked at the consequences of the use of social media during working hours.
